Chalcopyrite (yellow, centre left) is intergrown with bornite (brown-orange, left centre) and lath-shaped molybdenite (light grey, top right). Both copper-iron sulphides have altered to chalcocite (light blue, left and bottom right), which itself has a covelline rim (dark blue) associated with malachite (grey, poorly polished, left). Thin chalcopyrite spindles along (100) of the host bornite (left) have been preserved in chalcocite replacing bornite (left centre). Chalcopyrite (top right) has altered about its margin and along a fracture to covelline which shows strong bireflectance and reflection pleochroism (light and dark blue, centre right).

Bornite (red-brown, centre) contains abundant chalcopyrite (yellow) as spindles parallel to (100) and as rounded inclusions (centre right). Bornite has extensively altered to blue chalcocite (light blue), but chalcopyrite has been preserved. Chalcocite itself has altered to covelline (dark blue, centre bottom) along its margin. Quartz (dark grey, bottom centre) is the main gangue. A single crystal of malachite (medium grey, centre right) has grown into a void.The bornite-chalcopyrite intergrowth is a replacement or exsolution texture but can be seen to be earlier than the replacement of bornite by chalcocite.
